Water powered garbage disposal unit

ABSTRACT

A water powered garbage disposal unit characterized by the fact that all of the water that is used for flushing the garbage shredder is first used for driving such shredder, the admitted water first passing into an impeller chamber for driving the impeller and a shredder connected to it, and then passing into the shredder chamber for flushing the shredder. The device is further characterized by the fact that it employs driving gears which are sealed from communication with the shredder area or chamber so that garbage within such shredder chamber will not come in contact with the driving gears. Equally, the impeller chamber is sealed from the shredder chamber so that garbage in the shredder chamber will not come in communication with the impeller.

1 WATER POWERED GARBAGE DISPOSAL UNIT GENERAL DESCRIPTION A PREFERREDEMBODIMENT A preferred embodiment containing such improvements andrepresenting a present development of the invention is shown in theappended drawings.

In this drawing: FIG. 1 is an elevation section view. FIG. 2 is a topplan view. FIG. 3 is a side elevation view as if on'the left side ofFIG. 1.

DETAILED DESCRIPTION FIG. 1 shows a water powered garbage'disposal unitcomprising a casing having an open upper end 12 and a closed lower end13 and having a central shredder chamber 14. Casing 10has an integralsupplemental side or impeller chamber 15 below and to one side ofshredder chamber 14.

A water inlet 17 communicates to impeller chamber 15. A vertical sidepassage 19 in a-wallof the casing communicates with the impeller chamber15 and opens at 20 into the upper portion of the shredder chamber 14. Aside-drain 21 opens from the lower portion of shredder chamber Ahorizontalrotaryimpeller 23 in impeller chamber 15 is so positionedthatedge blades 24- intercept water flow from inlet 17 to side passage19 whereby impeller 23 will be rotated by water entered through inlet17. Inlets 17 and passage 19 are at substantially diametrically oppositepoints of impeller 23 and impeller chamber 15.

Impeller 23is mounted on a vertical drive shaft 25 joumalled at its endsin lower and upper horizontal wall parts 27-29 of impeller chamber 15.Shaft 25 has a pinion 31 in the hollow space under wall part 29.

A vertical driven shaft 33 in shredder chamber 14 is laterally spacedfrom drive shaft 25 and has its ends joumalled in upper and lowerhorizontal wall parts ing, all draining at 21.

All water flow from inlet 17 to side passage 19 is used to driveimpeller 23 and, thus, the shredder 41; and is also used secondarly toflush garbage at shredder 41 into drain 21. Thus, all the water that isused to flush the shredder will first be used to drive the shredder.

Total water supplywill be available for driving the shredder as well asfor flushing the shredder.

2 Since gears 31-37 are located in sealed chambers 30-38, they are notexposed to garbage in shredder chamber 14. Likewise, impeller 23 and itschamber 15 are sealed from shredder chamber 14 and, thus, are notexposed to garbage in such shredder chamber.

CONCLUSION From the foregoing it will be seen that there has beendisclosed here an improved garbage disposal unit of the water powertype, characterized by the fact that all of the water that is availableis used first to drive the shredder and secondarly, to flush theshredder. The

unit is further characterized by the fact that the drive gearing and thedrive impeller are sealed against being exposed to garbage at theshredder.

Now having described the water powered garbage unit herein disclosed,reference should be had to the claims which follow.

I claim:

1. A water powered garbage disposal unit comprising a casing having anopen upper end and a closed lower end and having a central shredderchamber;

the lower end of the casing being formed to provide an integralsupplemental impeller chamber below and connected to the shredderchamber of the casmg;

a water inlet passage opening into the impeller chamber;

said casing having a vertical side passage communieating with theimpeller chamber and opening into the upper portion of the shredderchamber of the casing;

and a side drain opening-from a lower portion of the shredder chamber;

a horizontal rotary impeller in the impeller chamber positioned so thatblades on its edge intercept water flow from the inlet to the sidepassage whereby the impeller will be rotated by the water passing frominlet to passage, these being at substantially diametrically oppositeparts of the impeller chamber;

a vertical drive shaft joumalled at its ends in lower horizontal wallparts of the impeller chamber and having a pinion fixed to it, above theimpeller chamber;

a vertical driven shaft in the shredder chamber laterally spaced fromthe drive shaft and journalled in lower horizontal wall parts of theshredder chamber and having a gear thereon meshing with the pinion andbeing below the shredder chamber;
